IMPROVEMENT lM'MAcHlMEs tot` BEMDme CORRUGATED SHEET METAL.

Sreciiicationforming part of'Letters Patent-N. $37,308. dated January' 6, 1863.

v Be it knownthat I, SAMUEL J.- Stimmt,i `of Brooklyn, in the `coujnty of'Kings and State of New Yfork., have' invented' a newand useful improvement in machines for'- bending corrugated sheet metal intofcylinders which are'corf rugatedaronnd their circumference; and Ido hereby declarey thatthe following is a full, clear, and exact description ofthe same,pref erence'V being had to the accompanying drawings, forming part 4of this specification, in which-. f

' Figure lis a side elevation and partial sectioh of my impreved'.machine.4 1 Fig'. 2 is a vertical transverse section of thf'a"sam e.fA Fig. 3 is a vertical longitudinal sectionlof the-same. Fig. 4 is a' corrugatedsheet of metal,'which is Fig. 5 is the, same sheet'as bent into cylinder form bymy machine.

Similar lettere-'of reference in the several Themain object ofmy invention is to man-- nfaetnre by machinery the cylinder or body of corrugated sheet-metal casks, and thus meet :the heavy demand 'for suclr casks, and at the same time reduce the cost of the same. 'Io

jviously-corru gated sheet, and, as the sheet is drawn through, it bends it gradually luntil it' given circle, and' ther several segments united necessarily constitute a full circle, and` this circle .is the desired cylinder form for tliecask body. My roller-die has' a rotary motion in inconcert with another part,`and the motion' of all the parts or rollers is` positive by means one part or-roller ofthe die meshfwith .the cordie. and the three rollersthus mesh 'together and each bites upon the corrngatedmctal sheet capable of being diminished or increased-in which have deep or" shallow und ulations.

lhe nature of my invention may be said -to consist in bending sheet metal which has been previously corrugated into the form of a cyl- Y uniform' motion.

inder which is` corrugatedaronnd its circumference by means of an organized machine,

which consists of three adjustable rollers 'llav ing corrugated circumfercntial.- snrfaces, said surfaces meshing into one another and also revolving in concert andi with a positive and To enable others skilledin the-art to make and use nly'invenlion, I will proceed to describe'its'construction and operation.

A A represent two 'strong -end standards bolted iirml y to a horizontal bed-pieceV or crosstie, B. These standards with the tie constitute'a simple substantial frame.

Gis a feed-ingtable arranged' onthe front. of the standards.' l

D D! D2 represent three rollers with corra-x gations or grooves aroundl their circumference.'

These rollers are of 'equaldiametery and are.

arranged within the frame, se that two bf them are on the same horizontal plane and-the oth erf above' them anddirectly over the valley formed between them, as represented?, vThe boxes s," in which the shafts of Athese .rollers turn, are

arranged in dilierent parts of a slot, t, of ,invertled-T form', said-'slot providingfor three-boxes.- There is a slot of .this'character in each of the end standards-.of the frame, and inl the same the boxesareadjusted by means of set-screws E F G. The `rollers D D' D? 'maybe ,solid with the shafts or axes on which lthey revolve but I prefer to make them' up of ashaft anda' series of ring-flanges 'of V'cr other similar form in their radial section from center to circumference, as repres'ented at ai These llange's are placed side by `side-one another on the "shaft, andfalternatelyform a 'groove' and-.a

tongue. The top' roller should have two more .flanges and'one, more groove'. than the lower rollersfand the flanges of the upper rollers should' be deep enough to lill the groevescf "the lower rollers; orjverynea'rly so, and so also should the flanges ofthe lower rollers match thegrooves of the'upper roller. When the rollers are in operationen the sheet of' metal,

the flan ges of' all the rollers bite upon it. Wheiithe sheet of metal is being inserted vbetween the rollers, the flan ges" of the respective rollers arenot in perfect meshing position; but after the sheet is inserted they are moved to that position by adjusting the shafts of the.

rollers. The extent of the depth lof entrance 'of the'respective flanges intol the respective grooves of the severalrollers is controlled or regulated by thejset-screws E FG.` It' it is desired to bends'hee'ts; having a sharpeorruf gation, thel rollers are moved up closer together bythe setlscrews butif 'it is desired togbend' sheets havin ga blunt eorrugation, the rollers are moved fartheriapnrt. The lian ges are con-r' fined on the shafts by collars,oneof which lcollars is constructed lwith a'nut, c, which fits 'a screw-thread, e, of theshafts, and thus binds the flangestogether. Itisv desirable to have therollers made of separatedflan ges, tor if` one of the flanges should be injured, its place can be lled by a perfect one." This is 4not the case with the rollers which have'the flanges-ft part of thev shaft.- JByprov-idingthe strongretainngscrews E E at .the ends of the top roller anyl desired twistfat one. end of the sheet of metal may be' imparted during the bending ot rit into the cylinder fo'rm by simply setting'one end of: this roller higher thanits other end.

The rollers lare all geared togetherv by cog#V wheels I [.Iof equal diameters, and with teeth long :enough to allow thel necessary adjustmeufs to the rollers. The power is transmit- Ated 'from a belt-shaft, J ,to the rollers by means ota pinion, KWhich gear'with a large spur- Wheel, L, ofthe front lower rollen.

` To bend a sheet ot"leorr'ngated metal, such as shown in Fig. 4, i'nto'th'e formshown in Fig. 5, the sheet is applied between the rollers, so .that its corrn'g'ations match the tonguesl and grooves of the rollers, and then is forced: o'r drawn forward until the circular or cylinv 'der bend 'from the front to therear end of the sheetlis imparted. The. sheet rolls round the upper roller as the bending' proceeds, and

when itis fully bentit has theform of that roller if permitted to take that form but,as

itis desirable to remove the cylindric article Without removing the rollers, I vsovcontrolth'e sheet as to prevent' the two ends or edges closing together. The article lis removedby moving the rollers from each other' and then springing the bent metal oli'. the roller.

What I claim asmy invention, and desire to Asecure byLetters Patent,- is

- Bending corrugated sheet metal in'tothje kform of a cylinder which is corrugated aroundits circumference by 4meansfof three adjustable rollers having corrugated circumferential surfaces, such as described, said .surfacesy meshing into one anotherand also revolving in concert and with an equal and positive mo-A tion, all substantially as hereiuset forth.
